Hi, im having trouble with the installation and compiling of some applications. I am running Fedora Core 2 and KDE release 3.2.3-0.1

Trying to install konversation and after ./configure I get the message. Configure good, now start make. but on doing that I get the error /usr/bin/ld: cannot find -lpng, this also happens with a fwe other programs im trying to install.

Being new to linux I have no idea what this means and how to fix it. Any help would be appreciated.
